Resumen
This paper summarizes the work carried out in a research project whose main objective was
to develop high-performance sustainable bituminous materials (using crumb rubber and additives
to reduce their manufacturing temperature) to be used in roads that support high tra c volumes
and/or severe environmental conditions. For this purpose, various studies were conducted both in
a laboratory and in a real asphalt plant (at binder and mixture level). Later, these materials were
used to construct a trial section in a highway at a mountain pass (at more than 1400 m above sea
level) supporting more than 2600 heavy vehicles each day under severe environmental conditions
(snow during winter, and high temperatures and many hours of solar radiation during the summer).
The results indicate the viability of using these materials, since they provide a number of advantages
such as improved workability at lower temperatures and an increase in the mechanical resistance
against the main sources of distress that a ect asphalt pavements.
